ICE-CREAM FREEZER.

Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed November 1, 1913. Serial No. 798,688.

To all whom it may concern Be it known that I, SABATINO DnMAnoo, of 296 Sauchiehall street, Glasgow, Scotland, confeetioner, have invented certain new and useful Improvements in and Connected with Ice-Cr ram Freezers, of which the following is a specification.

This invention relates to improvements in ice-cream freezers,.and has for its object to simplify the construction of such and thereby minimize the cost.

According to my invention, I form the frame carrying the scrapers of H-formation. On the upper end of the freezer or can there is a flanged ring or band on whose outer circumferences are formed teeth, which gear with a pinion wheel supported by means of a suitable bracket fixed to the outside of the wooden tub. The spindle of the driving or operating wheel passes through the said bracket and is connected to the pinion wheel. The freezer is retained in its proper position in the center of the tub by means of a ring or band which is placed immediately underneath the flanged toothed ringer band already referred to and is fixed to the two sides of the tub in any convenient manner.

The freezer can be operated by manual or any other suitable power.

In order that my invention may be properly understood and readily carried into effect, I have hereunto appended one sheet of drawings, of which"- I Figure 1 is a vertical section of an ice cream freezer embodying my invention; part of the section is taken through the tub and freezer while the other part is taken through the tub only. Fig. 2 is a plan taken at two elevations, one above the large bevel toothed wheel and one below it. Fig. 3 is an elevation of part of the scraper frame, scraper and freezer can. Fig. f is a vertical section, plan and front view of the arrangement for carrying the outer ends of the H-shaped frame, all hereafter more fully referred to and described.

A is the tub, mounted with a bracket A with depending fork A fitting upon the upper edge of said tub for carrying the driving spindle B, one end of which is mounted with a pulley C and the other end with a bevel pinion D. The said pinion D meshes with the teeth on the flanged ring or band E formed integral with or rigidly attached to the upper edge of the freezer can F. The freezer can revolves in a step bearing Gr and is guided and supported during rotation in an annular ring I l. The frame I supporting the scrapers J, K, is of the shape shown in the drawings, and more particularly in rig. 3, namely, of H-formation. The two outer arms I I fit into rectangular-shaped sockets L having inlets approached in opposite directions, as shown in Fig. 2, formed in the bracket L and are detachably connected. The same bracket is made to carry or support the ring I-I.

Claims:

1. In an ice cream freezer, the combination with a tub and a can revoluble therein, of diametrically opposite brackets projecting inwardly from the upper edge of said tub, a can supporting ring carried by said brackets, and an H-shaped so 'aper mounted in said can, said scraper having oppositely extending arms at its upper end shaped to removably lit into lateral sockets formed in opposite sides of said brackets.

2. In an ice cream freezer, the combination with a can and tub, of a scraper mounted in said can and supported by said tub, said scraper comprising vertical, substantially pa 'allel elements, an intermediate transverse member joining said elements, a central vertical arm depending from said transverse member for supporting the sc 'aper in said can, and oppositely projecting arms at the upper ends of said vertical elements for attachment to said tub.

In testimony whereof I afl'lx my signature in presence of two witnesses.

SABATINO DEMARGO.
